Authorities probing a well-heeled Upper East Side monsignor who allegedly bilked money from an elderly parishioner said his cup also runneth over with hundreds of thousands of dollars in undisclosed bank accounts – and a membership at one of the country’s toniest golf clubs.

The investigation of Monsignor John Woolsey has turned up a personal account with Smith Barney worth $450,000, a Citibank account with $200,000 – and a $340,000 discrepancy over a contracting bill for work done on the church.

And when Woolsey wasn’t saying Mass as pastor at St. John the Martyr, sources said he could sometimes be seen hitting the links at the Winged Foot Golf Club in Mamaroneck, an establishment so exclusive that visitors need a password to get on its Web site.

The Archdiocese of New York last month booted Woolsey from his pastorate at the East 72nd Street church and reported him to the Manhattan District Attorney’s Office after learning that cash in the “high hundreds of thousands of dollars” had disappeared from church coffers, said officials familiar with the case.

The criminal investigation came quickly on the heels of a civil lawsuit accusing the popular priest of bilking an elderly parishioner out of $500,000, including $100,000 that was used to buy a luxury condo on the Jersey Shore.

Sources said the probe of the priest’s alleged pilfering is still in its early stages.

The Queens contractor who reported the $340,000 discrepancy told officials from the DA’s office that he billed St. John the Martyr $160,000 for the work. But Woolsey apparently told the church the bills totaled $500,000. Officials said the Citibank account has both his name and the church’s name on it, but the archdiocese knows nothing about it.

The prestigious Winged Foot Golf Club usually draws doctors, lawyers and investment bankers.

Neither Woolsey nor his lawyer could be reached for comment.

Woolsey has denied allegations made in the lawsuit, and he has not been charged with any crimes.

The priest was sued in state Supreme Court by the estate of Rose Cale, a parishioner who died last year at 88.

The suit alleges Woolsey induced Cale into giving him $490,000 in cash and stocks, part of which was used to buy the Jersey Shore condominium.

He later sold the condo for a $167,000 profit.

A lawyer for Cale’s estate said the suit has since been amended to include the profit from the condo sale, and $1 million in punitive damages.

“None of this information surprises me,” the lawyer, Brian Caplan, said. “It’s plausible that my client is not the only victim of the conduct outlined in our complaint. They’re waiting to see how this unfolds.”
